The password encapsulation and obfuscation is really only a small part
of the whole transport layer security issue.  TCP is not secure (in any
meaning of that word), at least not alone over plain old IPv4.

Even the transport security is only a small part of the whole CVS
security issue.  CVS is not designed or implemented to be a security
tool -- it's at the level of /bin/ed in security terms, not /bin/login.
With CVSpserver there's lots of opportunity for one user to spoof
another -- i.e. there's _NO_ accountability in pserver.

SSH can be configured to use any of many forms of authentication.
There's no fundamental need to ever type passwords to it when it's used
as a remote job execution facility for CVS.
